Error "Cannot determine a valid Java Home" when launching Java Web Start (Windows 10)

I'm using a Windows 10 system.

I need to use a program, which is opened by clicking on a Windows shortcut. Checking the shortcut's properties, I see the following as destination:

C:\ProgramData\Oracle\Java\javapath\javaws.exe -localfile -J-Djnlp.application.href= "C:\Users\Pc\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\25\33dde299-6b4cf49f"

But when I double click on the shortcut, I get an error dialogue stating: "Cannot determine a valid Java Home"

The same happens if I simply double click on the javaws.exe executable.

I already tried setting the %JAVA_HOME% environment variable to a valid value, and rebooted the system, to no avail.

I may I solve this problem?
